The Ordnance Survey map of 1948 shows the area as farmland. In the 1960s, as part of Swindon's eastward expansion, the entire area became a privately built housing estate. Following a Community Governance Review in 2013, Nythe obtained independence from Stratton St Margaret, becoming a parish in its own right with effect from 1 April 2015. After a further review in 2016, the parish was extended to include Eldene and Liden, which were previously
unparished areas; from 1 April 2017 the name of the parish is Nythe, Eldene and Liden. The parish council has nine members,
Swindon Borough Council is the
unitary authority for the area; Nythe and Dorcan fall within Covingham and Dorcan ward, while Eldene and Liden are part of Liden, Eldene and Park South ward. For Westminster elections, the parish is in the
Swindon South constituency. ==Geography==
